The nervous system is a system in the body that sends signals or messages to other parts of the body. The nervous system is comprised on the central nervous system (brain and spinal cord) and the peripheral nervous system (comprised of the cranial, spinal, and peripheral nervous with motor and sensory endings). It lets people and animals respond to what is around them. The nervous system is involved in receiving information about the environment around us, through our sensation, and generating responses to that information (our motor responses).
The nervous system is integral to our body’s function playing a role in nearly every aspect of our health and well-being. It guides everyday activities such as waking up; automatic activities such as breathing; and complex processes such as thinking, reading, remembering, and feeling emotions. It also controls brain growth and development.
As you can see, the health of our nervous system is crucial to our overall health.
